the flour, baking soda and salt. Cream the butter and sugars with a
mixer on medium speed until fluffy. Beat in the eggs and vanilla
extract. Turn the mixer to low and add the dry ingredients gradually.

the bars into rectangles and set on wax paper. Add a tablespoon of

and spoon a thin layer over individual bars. Working quickly, use
pretzel pieces to assemble a ladder on top of each bar.
